Testing
It is recommended that applications of Statfree Dissipative
Floor Finish be tested periodically to ensure that insulative
contaminants such as dirt and grime are not building up on
surface. For optimal performance the surface should be
regularly maintained and kept cleaned. Testing for either
point to point resistance (RTT) or point to ground resistance
(RTG) will indicate if the floor finish needs maintenance.
If the surface is clean, high resistance readings usually
indicate that the floor finish is becoming worn and is in
need of replenishing of solids. These solids are worn away
over time due to normal floor traffic. Hence, the high floor
traffic areas will need more frequent maintenance than low
traffic areas. Maintenance is typically required if resistance
measurements are above 1010 ohms.

vERIFICATION TESTING
For quick and easy verification of surface resistance, Desco
recommends the use of our
19635 Pocket Megohmmeter.

MEGOHMMETER TESTING
Desco recommends the ESD Association’s Standard 7.1
test procedure along with a megohmmeter for determining
both RTT and RTG measurements. The Desco 19780
Surface Resistance Test Kit will provide all the necessary
equipment to test in accordance with the above mentioned
ESD Association standard. For detailed information on
the Surface Resistance Test Kit ask for Technical Bulletin
TB-3014. ESD-S 7.1 is available from the ESD Association,
7902 Turin Rd., Suite 4, Rome, NY 13440-2069, (315)
